Dab tsi yog cov yam ntxwv ntawm 18CrNiMo7-6 steel?

18CrNiMo7-6 steel muaj cov yam ntxwv hauv qab no:

1. Cov khoom zoo txhua yam:

• Muaj zog dabtsi yog khoov: Nws tuaj yeem tiv taus lub sijhawm khoov loj thiab lub zog shear, thiab tsim nyog rau kev tsim ntau yam kev tsim vaj tsev, xws li lub zog loj, cov ncej sib kis, thiab cov turbine shafts.

• Siab hardness thiab hnav tsis kam: Nws tuaj yeem txo qhov cuam tshuam ntawm kev hnav ntawm cov khoom siv ua haujlwm thiab txhim kho lub neej kev pabcuam ntawm cov khoom siv. Nws yog feem ntau siv rau hauv kev tsim cov khoom siv siab thiab siab ceev, bearings thiab lwm yam khoom.

• Lub neej qaug zog siab: Nyob rau hauv kev ntxhov siab, nws muaj lub neej qaug zog siab, uas tuaj yeem tiv thaiv kev puas tsuaj thiab tsis ua haujlwm thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv. Piv txwv li, nws yog siv rau cov khoom tseem ceeb xws li cua zog zog thiab cov cav tsheb.

• Zoo toughness: Cov tub ntxhais muaj siab hardness thiab toughness, thiab muaj peev xwm tiv taus kev cuam tshuam thiab kev co nyob rau hauv ib tug tej yam ntau yam. Nws tsim nyog rau kev ua haujlwm nrog qee yam kev cuam tshuam thiab kev vibration loads, xws li mining machinery.

2. Zoo heev hardenability: Vim yog qhov tsim nyog piv ntawm alloying ntsiab, qib steel no muaj zoo hardenability. Tom qab kev kho cua sov kom zoo, ib qho kev sib txawv hardness thiab lub zog faib tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom tuab lossis cov khoom nrog cov kab loj loj.

3. Kev ua haujlwm zoo: Nws muaj kev ua haujlwm zoo thiab tsim nyog rau ntau yam txheej txheem, suav nrog forging, txiav thiab vuam. Txawm li cas los xij, thaum welding, preheating thiab qeeb txias yuav tsum tau muab sau tseg kom tsis txhob muaj cov kab nrib pleb.

4. Siv dav: Nws yog dav siv hauv kev lag luam xws li cua zog, tsheb, petrochemicals, mining machinery thiab siv tshuab. Hauv kev lag luam cua fais fab, nws tuaj yeem siv rau hauv kev tsim cov khoom siv hluav taws xob cua thiab cua fais fab shafts; nyob rau hauv kev lag luam automotive, nws yog siv rau cov khoom tseem ceeb xws li cav thiab kis tau tus mob; hauv kev lag luam petrochemical, nws tuaj yeem siv los tsim ntau yam khoom siv tiv thaiv corrosion; nyob rau hauv mining machinery teb, nws tuaj yeem siv los tsim cov khoom tseem ceeb xws li crushers; nyob rau hauv kev tsim kho machinery teb, nws yuav siv tau los tsim ntau yam khoom.
